APPLYING DEVICE'.

t Application filed February My invention relates to applicators or de vices for applying a substance and more particularly a fluid to a materialfand has for its object to provide a simple device whereby a liquid may be eiciently applied in restricted quantity at will. Th'e `par.ticu lar object of the invention is the; provision of an applicator whereby a vchemical solution having the property of eradicating certain stains and blemishes from fabrics or other materials may be manually .applied in minute drops to the stain or other blemish in a manner to avoid injury to the fabric or other material. Other more specific objects of the invention will appear from the description hereinafter.

ln the accompanying drawing, which showsan example of the invention without defining its limits5 Fig. 1 is an external. view of a device adapted for removing rust and other stains from fabrics; F 2 is a longitudinal section on the line 2 2 of Fig. 1, and Fig. 3 is a sectional elevation showing another arrangement ofthe invention.

In :its illustrated example the device comprises a container 5 provided with an air inletor breathing aperture 6 and with a flooding apertureor water inlet 7, the two apertures being spaced from each other longitudinally of the container 5, said container being preferably constructed of a material, such as rubber or glass, which is not subject to attack by certain predetermined chemicals. .The container :5 may be of any suit- :fiblo shape and preferably is cylindrical in form with its one end tapering toward a point as indicated at S; a capillary opening i) is located at the apex of the tapering end and,scrves as an exit for a liquid. as will appear more fully hereinafter. -The other end of said container. in the illustrated eX- ample, is screw-threaded to rece-ive a removable cap 10 which tits against a packing 11 of suitable material to withstand the action of the previously mentioned chemicals; this packing 11 not only seals ther container 5 in a fluid-tight manner but also protects the ap against contact with such liquid as may be contained in the container 5. A shell 12 is removably fitted upon the capped end of the container 5 and is held in place thereon by friction or, if desired, said shell may be screw-threaded upon the cap 10; the container 5 may be provided with an annular bead 13 to arrest the movement of the shell 12 upon the container. In any case the de- 14, 1925. semi No. 9,141.

vice is of elongated form and is lconstructed so as to be capable of being easily grasped andheld in the hand in the manner of a pen or pencil. y The illustrated example shows the device in a form particularly adapted for applying a chemical solution adapted to eradicate rust and other stains from fabrics or the like.. Forthis purpose a snitablechemical, that is, any chemical, either in stick. or crystal form, having the property of converting iron rust into soluble fornn such for example as a water soluble compound of fluorine having an acid reaction, is contained in the con'- tainer 5. the drawings showing` said chemical in the .form of astick having itsone end pointed as indicated at 15. lVhen in place in the container 5, the stick 14 extends lengthwise thereof with the pointed end 15 projecting' toward `the opening 9. The diameter of the stick 1li is initially such that it is stopped by the taper of the end 8 at a distance from the opening 9 and so tl at said stick acts in the nature of a plunger as will appear more fully hereinafter.

In practico the chemical or its equivalent, appropriate for the purpose 'for whichithe device-.is intended, that is for instance the stick le, is kplaced within the. kcontainer 5 after which the device is ready for use. AS- suming now that it is desired to remove a rust stain from a handkerchief, the tapered end of the device is dipped into clear, clean water to an extent to bringthe aperture T beneath the water but to maintain the aperture (i out of the saine. The device is held in this position for a short peri-od to allow a restricted anionnt of water to flow through the aperture, 7 into the container After the aforesaid restricted quantity of water has passed into the container, the apertures (i and 7 are covered with the forelinger and the device is lifted from the water. lith the forelinger still in position over the two apertures, the device is now brought to a horizontal position in the hand and is gently shaken for a short period so that the water in the container will dissolve a restricted quantity of the chemical 14 contained therein. lith the forelinger still in place over the holes, the tapered end of the device is applied to the rust spot after which the'tinger is removed from the apertures 6 and 7. The dissolved chemical will now How through the opening 9 from the tip of the container on to the rust spot. The tapered end of the device may be used to spread the chemical solution over the aforesaid rust spot and to work it into the same in order to bring about the complete removal of the rust stain from the aforesaid handkerchief. In this way the small amount of solution which is required for an ordinary rust stain is applied while the handkerchief is protected against injury resulting from an overapplication of the solution and its spreading beyond the stain over the adjacent unstained parts of the handkerchief.

lith the device in question, the chemical, either in crystalline or solid form, is thus so packed that dipping of the device in water will cause enough water to pass dinto the container and into contact with the chemical to dissolve the same to a small extent and to create the small amount of solution which is required. The latter, as previously stated, is expelled in driblets through the opening 9 as wanted.

The shell 12 in addition to providing an increased axial length whereby the manipulation of the device is facilitated may be used also as a receptacle for additional chemical or for a reserve stick 14+. as shown, instead of utilizing the shell 1Q for containing a reserve stick 14, it may be utilized to contain a chemical or combination of chemi cals in the form of a liquid, crystalline mass or amorphous stick or in powdered form to be used for removing` ink spots from fabrics or other materials or any other spots or stains for which the chemical or combination of chemicals is particularly adapted. Or if desired the container, after having been used, may be detached from the shell and inserted into the same in a reversed con dition as shown in Fig. 3; in the latter case the shell serves as a protector for the container.

It will, of course, be understood that the device may be used for other purposes than that described and illustrated.

Various changes in the specific form shown and described may be made within the scope of the claims-without departing from the spirit of my invention.

I claim:

l; An applicator for an eradicating solution, comprising an elongated container provided with a breathing aperture and a water inlet adjacent said aperture and spaced therefrom longitudinally of the container, said container being adapted to receive a stick of soluble chemical, one end of said container being shaped for working the solution into a fabric and being provided with a capillary outlet for said solution.

2. An applicator for an eradicating solution,` comprising an elongated container provided with a breathing aperture and a water inlet adjacent said aperture and spaced therefrom longitudinally of the container, said container being adapted to receive a stick of soluble chemical, one end of said container being shaped for working the solution into a fabric and being provided with a. capillary outlet for said solution, a cap for the other end of said container, and

a hollow extension removably fitted upon said cap.

In testimony whereof have hereunto set my hand.
